I just built my new computer with a new ssd where my operating system is on. I also have two 1tb hard drive in raid 0. When i installed everything worked great until i noticed in my computer that my raid drive was not visible. I opened my intel matrix storage utility and there it was visible, plus it was also visible in my device manager. what step did i mess up on? i would appreciate the help since i need to back up info from my old pc to this new one one those drives

Just the one partition, which is used for pic, documents, etc.. my games, operating system, whatever, i want for performance goes on my ssd. the reason i went with mbr is because everywhere i read said to use gbt only if it was highter then 2tb. what is the difference performance wise?
